Application filed October 24, 1907. Serial No. 398,935.

To all whom it may concern:

Be it known that I, JOHN T. Know, a citizen of the United States ofAmerica, and resident of Fort Wayne, in the county of Allen and State ofIndiana, have invented certain new and useful Improvements inValve-Operating Mechanism, of which the following is a specification.

This invention relates to improvements in valve operating mechanism ofthat class used for flushing tanks for water closets, and the objectthereof is to afford simple mechanism of its class under control of thehandle which may be operated by turning in either direction. This objectis accomplished by the construction illustrated in the accompanyingdrawing which is a vertical section of a portion of a flushing tank,partly cut away, and showing the relative arrangement of parts of thevalve and operating mechanism.

Referring now to the numerals of refer ence marked upon the drawing: 1is a flushing tank, and 2 is the internal metallic lining therefor.

3 is a hollow valve adapted to close the discharge opening 41 whichleads through the bottom of the tank. The valve has a stem 5 whichextends upward from the valve loosely through a guide 6 which projectsfrom the side of the overflow tube 7, and the stem of said valve is bentat right angles at its upper end 8. A shaft 9 extends through the frontof the tank, and upon its outer end is fixed a handle 10, and upon itsinner end a crank 11, the latter having a pin 12 the center of which isout of alinement with the.

axis of the shaft 9. A swinging arm 13 is connected at one of its endswith the crankpin 12, and at its other end has an integral T piece 14.To the lower end of the T piece 1% is loosely attached a connecting rod15, the lower end 16 of which extends at right angles. That verticalportion of the valve stem 5 which extends above the guide 6 passesloosely through the bent end 16 of the connecting rod 15, and said valvestem is adapted to be lifted when the connecting rod is raised and itsbent end comes into contact with the bent end 8 of the stem 5.

A strut 17 is pivoted at one of its ends to the upper end of the T piece1 1 at the outer end of the arm 13, and at its opposite end to a stud 18which extends from the inner face of the front of the tank at a pointhigher than the shaft 9. The strut 17 is adapted to swing upon the stud18 and its outer end therefore moves in the course of an arc of acircle, the center of which is coincident with the center of the stud18. When the crank 11 is turned pressure is exerted at the outer end ofthe strut 17 because of the connection of the arm 13 with the outer endof the strut and crank-pin, and the strut will thereby be moved upwardlyby the outer end of the arm. The connecting rod 15, being connected withthe outer end of the arm 13, will likewise be raised and, in turn, thevalve 3 will be lifted from its seat, allowing the liquid contents ofthe tank to pass through the opening 4 by gravitation. The crank-pin 12is so located with respect to the other moving the arm 13 will be forcedtoward the point of its connection with the strut 17 when the handle 10is swung in either direction, and the outer end of the arm thereuponmoves upwardly guided by the swinging end of the strut.

Having described my invention, what I claim as new and desire to secureby Letters Patent is 1. In apparatus of the class described, a tankhaving a discharge opening; a valve in the tank adapted to normallyclose the opening; a shaft extending through the wall of the tank; ahandle fixed upon the outer end of the shaft; a crank fixed upon theinner end of the shaft; an arm having connection at one of its ends withsaid crank; a connecting rod having pivoted connection at the outer endof the arm and engagement with the valve to actuate the latter; a studprojecting from the inner face of the wall of the tank; and a strutpivoted at one of its ends upon the stud and having connection at itsopposite end with the outer end of the arm.

2. In apparatus of the class described, a tank having a dischargeopening extending through its bottom; a valve within the tank adapted toclose the opening; a crank; a handle for operating the crank; an armhaving connection at one of its ends with the crank and at its oppositeend connected re lation with the valve to lift the latter; and a struthaving pivoted connection at one of its ends to a stationary pointhigher than the crank, and at its opposite end with the outer end of thearm, the strut being adaptparts that with the corresponding end of thearm and being adapted to guide the arm upwardly when the latter isactuated by the crank.

In testimony whereof I afiiX my signature in presence of two witnesses.
